Lindsay Lohan -- Spirit of the Night

Lindsay Lohan -- Spirit of the Night

2/16/2009 1:05 PM PST BY TMZ STAFF

Lindsay Lohan pulled an all-nighter in NYC, but we're pretty sure she wasn't hitting the books for her alcohol ed class.

Lindsay rolled up to Chace Crawford's pad at 6 AM. She was quick to point out there's nothing between her and Chace because he has a GF. So does Lindsay, at least 3 days out of the week, when she hasn't gone nuclear on Sam.
